Same as title. I used it for 1 month and it work well. A few moment ago I tried to upload code to arduino mega and I can't find arduino's port anymore. It was dissapear. But my arduino board seem still work ( led power still work and led pin 13 still work when plugged in and press reset )
I tried to find arduino's port in device manager, but it seem disappear ( I saw it yesterday, but it's not here now ) :o
What should I do now ? I'm a newbie with bad english. Plz someone help my arduino
If the ON led does not light when connected, it's not normal. If the pin13 led does not light, you can give the board a reset and it should flash 3 times.
If anything connected to the board, disconnect everything and try again.
I used 8 bit led digital tube to connect. Also my ON led still light, but when I press reset the led on pin13 blink 2 times. I tried to connect this jumper. But my PC ( also with other PC ) still can't found my arduino.
update: I touched the crystal 16Mhz and TX led light up ( tested with no connected to PC ). Is that normal ?
